Fujian Yangdun hydroelectric generating units contracted by our compnay to is now the largest shaft tubular unit in China.
the research project has been adopted in major scientific and technological innovation patent in Hangzhou.(Project No.: 20092111A01). In May 2012, the project has passed the acceptance of Hangzhou Science and Technology Bureau,
and awarded with first prize of Kunlun Science and Technology of Ministry of Water Resources.
Features of Shaft Bulb Turbine Unit
1. The speed of units can be increased by 4 - 6 times, the size of the generator is greatly reduced.
2. Reducing the size of the generator, the generator is moved into upstream of the concrete shaft, the structure becomes simple.
Solve the ventilation problems bulb turbine generators.
3. Since the size of the generator and the manufacturing difficulty is reduced, the unit cost can be greatly reduced.
4. Tubular shaft unit is designed to save cost of the whole unit. Compared with traditional bulb tubular unit, the cost can be reduced
by about 30%, improves economic indicators of power plant,makes the development of whole project possible.
